17 tips to extend battery life on Windows Phone 8

We love our smartphones, but one issue that might come up is battery life. If you’re a heavy user, you want to find ways to be able to use the phone as long as you can before needing to recharge. We have included 17 tips to extend your Windows Phone 8 battery life, but many of these tips involve turning off services and features. You decide which services you’re willing to let go to save juice. You don’t need to follow all of them, but following some will help extend the battery life on your Windows Phone 8 device.

Head past the break to read our tips with screenshots and video.

1. Use battery saver

You can set your phone to automatically save power when the battery level is low. Head to settings > battery saver, and turn it on. It turns off some services while in standby to help preserve battery life, but you will still receive calls and texts.  Emails will have to be refreshed manually.

Even if your battery charge isn’t low, you can manually turn on battery saver by clicking the advanced button. You’ll have three options: when battery is low, now until next charge, or always (not recommended). You know it is active when a little heart appears over the battery icon on the status bar.

2. Turn off unnecessary sounds

Select only the sounds that you need. You can turn off certain sounds by going to settings, then ringtones + sounds. We like to turn off the sounds for key press, lock and unlock, and camera shutter. We like to keep notification sounds on. If you receive a lot of emails, you may also want to turn off the sound for new mails.

3. Set glance to peek (Lumia only)

Glance on Nokia Lumia Windows Phone 8 lets you take a look at clock and notifications when your phone switches to standby. You can choose to turn this off, but it’s a cool feature to have. Head to settings > glance, then select peek. This option lets you see the glance screen when you hover your hand over the phone. Don’t forget to set the start and end times.

Glance

4. Turn off double tap to wake up phone (Lumia only)

Double tap to wake up phone is another cool feature to have on Nokia Lumia devices, but you can turn this off to save battery life. If you’re happy with pressing the power button to wake up the phone, then there shouldn’t be any problem turning off this option.

5. Lower the auto screen brightness

By default, your screen brightness is set automatically on medium. You can change this. Go to settings > brightness. Switch off the automatically adjust option and switch the level to low. Turn back on the automatically adjust option for a lower auto screen brightness that can help conserve battery.

6. Prevent some apps running in the background

Some apps may run in the background unnecessarily. If you don’t want them running in the background, go to settings > swipe to applications, then tap background tasks. Tap the app you want to block, and tap block.

Background Tasks

7. Turn on airplane mode

If you're listening to music or using your phone, but don't want to make or receive calls, you can switch airplane mode on. It turns off cellular, Wi-Fi, Bluetooth, and NFC sharing in one try, but you can individually turn them back on if you need to.

8. Turn on NFC or Bluetooth only when needed

If you don’t use NFC sharing or Bluetooth often, we recommend turning them off. Reactivate these features only when needed. Go to settings > tap+send or settings > Bluetooth to switch them off.

Bluetooth and NFC Sharing

9. Set to check for new mail less frequently

If you have added email accounts that don’t need to be checked frequently, you can change how often your phone downloads new content from those accounts. Instead of 30 minutes, change it to hourly, every 2 hours, or even by manual request only. Go to settings > email+accounts, then click on a mailbox account. Change the frequency under “Download new content.”

10. Decrease screen time-out

You can set the screen to automatically switch off after a short time. Go to settings > lock screen, then scroll all the way down to where it says “Screen times out after.” The shortest time you can choose is 30 seconds.

11. Keep Wi-Fi on when screen switches off

It’s more efficient on the battery when Wi-Fi connection is used to connect to the Internet, rather than a mobile data connection. To keep the Wi-Fi connection on even when the phone screen switches off, go to settings > Wi-Fi > advanced, and tap the Keep Wi-Fi on when the screen times out check box.

12. Stop scanning for new Wi-Fi networks

If you have already added your Wi-Fi networks at home or office, it will be more battery efficient to stop the phone from scanning for new networks in the background. Go to settings > Wi-Fi > advanced, then uncheck “Notify me when new networks are found.”

WiFi settings

13. Disconnect Xbox Live

If you don’t care about uploading games scores and achievements to Xbox Live, you can prevent your phone from connecting to the service. Go to settings > swipe to applications > games, then turn off “Connect with Xbox.” This is really helpful if you actually have more games listed under “other” compared to Xbox Live compatible games.

14. Disconnect Xbox Music

If you don’t use Xbox Music, you can disconnect from the service. Go to settings > swipe to applications > music+videos, then turn off “Connect with Xbox Music.” You can also turn off Xbox Music cloud collection from here. This doesn’t affect users who prefer to listen to music with other services like Pandora, Spotify, or Nokia MixRadio.

Xbox Games and Music

15. Close apps you are not using

If you know you’re done using an app, press the back button to exit instead of pressing the Windows Phone key. If you have the latest Windows Phone 8 update 3, you can also exit apps by pressing and holding the back button then clicking the X’s on the upper right corner of the apps you want to close.

16. Ensure that your phone SW and apps are up-to-date

Some updates bring bug fixes and optimizations that may be beneficial to your device’s battery life. Make sure you have the latest phone software by going to settings > phone update. For app updates, go to Store > Updates.

17. Use power cases or portable USB chargers

Another way to extend the battery life of your Windows Phone 8 device is to use accessories. There are portable USB chargers like the Nokia DC-18 and cases with built-in extra battery like the camera grip for the Nokia Lumia 1020.

Nokia Camera Grip

So those are some tips to help you extend the battery life of your Windows Phone 8 device. You don’t have to follow all our tips, but following some of them may help.

If you feel like your battery is draining unusually fast, restart your device by pressing and holding the power and volume down keys simultaneously until the phone vibrates. Release and the phone will restart. If you feel it’s still draining fast, the battery may be wearing out and requires replacing. You may need to contact the manufacturer for support.

siddhant_96 says:

That helped big time...thanks:)

Yakkob says:

Biggest saving i have found is turn vibrate off. See thread in Lumia920 forum

aitt says:

Fortunately for me I keep chargers around, but in all honestly the battery life is so outstanding on my 1520 I could go a whole day and not need a charger till I get home.

DeriQuan says:

Definitely agree with that. Batt life on 1520 rocks!

I have gotten 2 days and 3 hours before it turned off. If i keep it on Battery saver the entire time i can probably get more.
 

The difference in battery life over the 1020,920 and 900 is Night and Day.

The Snapdragon 800 is amazing at preserving battery when the phone is idle. Qualcomm definately didn't lie about that one.

 

VernonEL says:

Yes, battery life on my 1520 is phenomenal! I'd say a good 30-40% longer than my 920.

Jack Larson1 says:

I like the 1520, but I have to say, my 920's battery has improved immensely with the amber update. I can leave it unplugged for the night now.

Lucky. The battery life on my Lumia 920 is utter trash. I've already done everything on this list months ago, and still hasn't worked. I don't use my phone as heavily as some others might either. I don't know what the heck is wrong. Maybe I should take in and get it checked up.

Definitely take it to a store and have them look at it. My 920's battery is phenomenal, and I'm a light-moderate user. I keep double-tap-to-wake turned on, glance on peek, wifi always on, NFC always on, and I can still get from 6:50am to about 10:00pm without a charge. During the day I browse reddit via Readit, send texts, watch videos, play a few games, and I still have great battery life, so something must be up with your device. Also, consider restarting your phone occasionally to shut down "closed" apps for good. 

HaibaneReki says:

Ad 15) I thought apps were dormant when minimized except if not specified otherwise in the settings?!

d3d9 says:

don't they still take up some RAM?

elmacho says:

Unused RAM is wasted RAM.We`re talking battery life here.

elmacho says:

This ^^.Its pushed to the backstack,doesn`t draw battery at the time.

leoniDAM says:

the apps that are not in foreground are always in dormant state, except for those apps that use GPS. The apps can also prevent the intervention of the lock screen, but if you leave the app (for example if you press the start bottom) the app goes to dormant state. In this state an app don't use CPU, every tasks are stopped, doesn't use any connection, doesn't use GPU, it is only loaded in RAM but the power consumption of the RAM don't depend by occupation, if the RAM is empty or full the power consumption is always the same. Instead if you haven't the app in RAM there is more power consumption because the CPU must do more work (the compilation must be finished, and the app must be loaded in RAM), but if the app is gust in RAM this work is not necessary and there's less CPU usage. So leave the apps in the tasks switcher!

SwimSwim says:

This is true, but some apps can still abuse background tasks if you leave them open. The majority of apps and games will simply be tombstones, but some (like music or video apps), are still allowed to do background stuff even if they're disabled in the settings, so long as the app is open.

As such, just to be safe, closing an app (so that it doesn't appear in the multitasking menu) can help avoid it sucking juice.

But for the vast majority of apps, as you said, they'll merely be suspended, and not using resources.

leoniDAM says:

Sorry but this is completly wrong!
No apps can runt tasks in background!
The only apps that can are those apps that use continuous tracking of the GPS location, that run in the background if you permit it (by leaving the app enabled in background task).
The other apps can use only background agent that can run at least every 30 minutes and for a maximum of 25 seconds but the background agent are not connected to the apps but are a little small separated app that do some little stuff instead of the main app, and that run indipendently if the main apps is in the task switcher or not.
Also the background audio agent and the background file trasfer (i believe that you refer to this)are indipendent from main apps and their execution don't depend on the presence of the main app task switcher.

DalekSnare says:

Removing apps from the task switcher doesn't disable any background tasks. You have to disable the background task in settings if you want to do that. Closing tombstoned foreground apps will only waste power when you end up switching back to that app and it has to load more than it would have if you had left it tombstoned.

jaywinjv says:

Yeah, that tip is bulls**t. WPCentral need to get its sh*t together. ;)

gandhirushi says:

Excellent tips! Keep up the good work WP Central.

indieimprint says:

Don't play Asphalt 8

jklier says:

Also, don't use Waze. My charger can't even keep up with the power thirst that app has. On the positive side the phone makes a great hand warmer after using Waze as long as you don't mind first degree burns. :)

And don't play MS Minesweeper too... Turn off your data and location when not in use.

jibreezy1982 says:

Also Total Conquest!!

MrWhiteman says:

This aint a joke, Total Conquest will jizz your battery before you can say Bob's your uncle. I've got my 920 plugged into a 1A charger and the battery still drains while playing TC

KrisJoeEll says:

One question - Is playing games (like asphalt 8) while charger plugged on bad for battery life?

Good question.

Because of the charging process and the game heating up the phone, the battery gets hot. As higher the temperatur of a battery the shorter the life time. But your not playing it 10 hours. But if the battery is charged already and you play it still connected it is better for the battery. Think about the other option you have. Charing the phone, unplugging and playing, charing again after short time.... and so on. This will result in a lot more charging cycles and thats what makes the difference. 

In generell: wait with your heavy load tasks until your on usb. But actually.... use it as you like. 

 

KrisJoeEll says:

That's very helpful. Thank you :D

In my phone, under music + videos settings, there is only 'suggestions' available.

KrisJoeEll says:

They are referring to Xbox music which is not available in India.

ronty says:

But I live in India & these options are available on my phone.

avigyan says:

Even I live in India with my account region set to US. Too bad MS doesn't have Xbox Music here coz I like its features. Once tried the trial for a month before I was left with no option to use it anymore.

pookiewood says:

Stop scanning for new networks.  Durrr.  Why do I still have this?  That's a small thing that makes tons of sense considering I could just scan for WiFi when out an about and I can just ask if a loation has free WiFi.
 

SwimSwim says:

Yeah, never occurred to me either. Like I literally /always/ dismiss the notification, because I typically use my data connection (I don't use enough data each month, and I don't trust most public WiFi). And when I do connect to a network not already set up, I still end up accessing the menu via the settings anyways.

Sigh, silly, silly me. Not a big concern, though, because I've always gotten great battery life on my phone.

Shad0wguy says:

One of the biggest battery savers for me is to change the highest connection speed from LTE to 4G.  4G is still plenty fast and doesn't kill the battery as quickly.
 

ronijs19 says:

LTE is 4G

I know, in your country HSDPA is 4G not 3.5G like all others.

Shad0wguy says:

Yes, I know what you mean.  But it is listed as 4G in the phone, otherwise I would have just called it HSDPA+.

neogodless says:

How do you switch this?

schlubadub says:

Doing some home renovations? Almost time for the grout! :P

Can you see me, I'm about to install grout into tile in 2 bathrooms

dkxs says:

Where do you get the settings for music and video? How come my Lumia 1520 and Lumia 920 both don't have the settings shown in the screenshots? Mine simply has a suggestion to Microsoft button. No Xbox music collection etc.

shadow118 says:

My 620 also has only the suggestions button. It's probably region specific

rain620 says:

I gather we're all not connected to Xbox Music.

Reliv83 says:

18) Use 3G only when needed.

totally agree. and surprised it was not in the 17. wpc, why not edit the article and make it 18 to include this. one of the biggest drains in my experience

Thanks for this! 

 

Some of the tips on the background apps, games and music, I wasn't aware of, so found it really helpful. What was even better is the explanation as to why you suggested each point. Much better than the usual, turn off 4G, turn off this, that and the other...

Craig Smikle says:

If this article was being true to spirit it would say "turn Glance to 'off'". You just barely mention one can turn it off, and don't even say that would net you way more savings. It's purported as a cool feature to have, but then a bunch of other cool features are fair game for slaughter.

For me personally I don't see the point of keeping it on.

adrian1338 says:

the point is you dont need to turn the phone on to see time and notifications

Craig Smikle says:

If, (unlike double-tap to wake thing) you use overall less power keeping Glance Peek on (and watching for hover) than you would occasionally turning the phone on and back off to check the time, then I stand corrected. My meaning was that if Peek drains more power than Off then Off would make sense in an article about saving battery. If it doesn't, well good.

Separately from the power thing, I personally found it uncomfortable trying to hover over the phone each time and felt speedier just waking it up.

The "spirit" is to give tips in order to save battery, not tell people what to do with their phones. It's kinda interesting, internet is so democratic that every one thinks that their way of doing things should be mimicked by everyone else.

theavrgjoe says:

Just like a Progressive telling everyone that this is a democracy, but that you have to vote the way the Progressive wants you to vote.

Glance on peek is one of the best features when it comes to battery saving, especially with the new Black update! You save lots of power by not having to turn the screen on every time you want to see what time it is or check your notifications....

rain620 says:

I believe it makes the sensor turned on forever instead of the screen.

jaywinjv says:

I believe it makes sense that the sensor turned on forever instead of the screen turned a few times.

musarator says:

they should add an option to activate glance by short press on the camera button or something like that.. that way it wouldn't drain battery with the sensors or the touchscreen.. just a simple button..

mtsmedly says:

I'm just glad to see someone else is going through the trials of tiling their own floors like I am right now. Dang it's hard work.

In Limbo says:

I haven't seen an article this informative in a little while. I actually didn't know that you could adjust the "relative" brightness while still using the auto setting. Thanks guys.

wpguy says:

Me neither, although on my 925 it is hard to tell the difference between low auto and high auto.

schlubadub says:

I'd recommend turning off mobile network data if you don't need it for long periods e.g. at home or work on WiFi all the time. I also like to set the mobile network data "highest connection speed" as low as possible... E (Edge) in my case, probably "2G" for others. That's more than fine for general background data traffic

marky_yo says:

Thanks for the WiFi network one!! Hate that! Never got around to finding where to shut it off.....
Great help!

jfivieght says:

Keep phone in pocket :) More human interaction...

erzhik says:

Turn off data if you are not using it. Turn off location services if you don't need it.

uselessrobot says:

I do most of these and I find normal battery life to be quite good. The fundamental problem, however is with gaming or heavy app usage. I don't know what the hell it is with Windows Phone that prolonged use of an app that eventually results in excessive and unexpected battery drain. I find that if an app is making your phone run hot, it's only a matter of time before you find rapid battery drain even when the phone is idle.

This is probably my single biggest frustration with Windows Phone. I was originally inclined to believe it was the hardware, but it seems to be widespread across all Windows Phone devices which implies the OS. I've been in too many situations where I was out, with no means to charge the phone, and found the phone dead or almost dead. And this was after heading out a couple of hours earlier with a fully charged phone or close enough that it should never be a problem.

Even during gaming, the amount of load the same game places on the phone seems to vary. In some instances it runs considerably, and alarmingly hotter than others. So the best solution to extending battery life on your phone is to not play games, but especially avoid games that make your phone run hot.

Noam Bonnie says:

Agreed, phone tents to get into a spiral draining loop, and the only thing to stop it is a restart. Doesn't happen as often as it used to but it still happens and it makes the phone unreliable.

danielgray says:

Airplane mode on then off usually fixes this for me

elmacho says:

Background tasks,battery drain will be fixed with WP8.1.It`s a mess with WP8,they`re aware of it.

bruteech says:

Awesome list. Especially for new users.
It's also good to keep the app list tight. Don't keep apps that you don't use or really need.

ViktorG says:

All this things are from the 'Duuuuh' list. But lets admit - most of the time the reson why people don't turn off they bluetooth or airplane mode or NFC etc etc is because it's not as quick as in Android OS. To do all this on/off stuff you have to know where in Settings it's located and then drill down. In android - pull-down status menu is super, and I repeat SUPER awesome thing. I wish WP would implement status menu too. 

Jf.Vigor says:

They are in 8.1
But you're right

920Walker says:

I wasn't aware of that, can't wait. My biggest peeve after switching to WP a year ago.

deloa84 says:

I would have to agree. I downloaded an app that gives you the option to pin it but still it is OK...

psiu_glen says:

Or less need to. I don't miss micromanaging the phone to eek out an extra few minutes. I get that some people a) like that or b) need other features so they deal with it, but for me, the phone is an appliance/device. Not a portable desktop computer, per se.

Seems like both iOS and WP, in general (IN GENERAL, not every case), manage things like NFC/BT/WiFi/etc better than Android.

swissrc says:

Glance not available for 625 ?

Antistatic says:

Well... if you don't have it on your L625, you shouldn't be to sorry. It's nothing to have really...

I still doesn't understand why Nokia made this choice that is totally pointless, drains your battery and even making your display light up in your pocket... I question the prority that Nokia did when they made the glance function before the possibility to choose your own SMS-tone really... but hey...maybe it is just me...

quytam says:

I didn't know for nbr 5)

I thought that auto mode will overrule the setting, thanks for the tip :)

Antistatic says:

Edit: Posted reply on wrong post :-)

taymur says:

I dont think the brightness tip is right. Automatic brightness overrides the low, medium, and high settings.

poddie says:

I have to agree... if the tip is right, it would be very poor interface design. I also don't understand why you would use the volume down plus power trick to reboot, which I believe does not issue a controlled shutdown and is intended for use in lockup. Much better to just hold power and slide the screen down, which goes through the full shutdown process. Strange tips.

tgr42 says:

The tip is actually right.  It is very poor interface design - very counter-intuitive.  But that's the way they did it.

Munkeyphyst says:

What if I told you there is an automatic low, automatic medium, and an automatic high

kevinxb says:

It is definitely right. Try it in a dark room and you'll notice that the phone will stay at a high, medium or lower general brightness but still automatically adjust when you have the feature activated.

Nakazul says:

Some phones do this and some don't.

schlubadub says:

You should definitely set auto OFF, and leave it on medium (I find Low is too low in daylight). Auto means it's using the light sensor and constantly adjusting itself

tgr42 says:

This works differently on different phones.  On the 1020, auto on + low allows the display to become much dimmer in the dark than auto off + low.  Stupid, but that's how it works.

taymur says:

Auto has a wider range of brightness, so, low is not the lowest, and high is not the highest if you take into consecration the sunlight readability feature.

abhishake620 says:

Location was not listed .... Else as said duhhh isnt it obvious....

adrian1338 says:

Well - glance timer is not for when its in peek mode or not but rather when the night mode(red colour instead of white) is active

DJCBS says:

Nice article.
Never remembered to turn off Xbox Music!
Everything else I already do or deliberately don't do (I don't use Glance but Double Tap is a must be on to me, for example).

Now a question: why should "keep Wi-Fi on" be on to SAVE battery? How does a feature to keep something running help NOT draining the battery?

poddie says:

Because if wi-fi is off the phone will use the LTE connection to update email, etc, which uses more battery. Plus if you turn the phone on frequently it has to reconnect every time, rather than just maintaining the connection.

DJCBS says:

Ah so the wi-fi on is just for those who have cellular data always activated.
Ok, got it.
I seldom use my data connection as I normally always have access to a Wi-Fi signal (go Fon!) so I was wondering why on Earth would keeping Wi-Fi on would save battery.

By the way...am I the only one who has had problems with the "always on" Wi-Fi? Sometimes, when I had it turned on, it would turn "off" WiFi when I waken the phone using double-tap. It was something that only happened from time to time. So I turned the "always on" off anyway, since the phone connects quite quickly. But it was annoying.
(Not sure if that was corrected with GDR3 since I never used the feature again)
 

poddie says:

So if you have the data connection switched off, and do not have the "wi-fi always on" turned on, doesn't that mean that your phone has no data connection when the screen is turned off?

I have not had any issues with leaving wi-fi always on... currently on GDR3, but used Amber extensively as well.

'Because if wi-fi is off the phone will use the LTE connection to update email, etc, which uses more battery'

that is assuming you have email etc updates being pushed through. if you don't have such things leave 'keep Wi-Fi on' un-ticked

Arpit Mittal says:

I am using all these except 5 as screen brightness is always low with automatic off but sone is not using like double tap as I have Lumia 720, no email as using metromail, my battery is around 35-40 hours

13 and 14 were helpful. I had no idea that these services were running!

Joene90 says:

The wi-fi ones are clever, hadn't thought of those. To be honest, I don't think I knew there was an advanced button under wi-fi :p

One thing I've been doing when my Lumia 920 does random drains - hasn't happened for a while though - is turn on flight mode, then turn the phone off. Turn it on after a minute or two and when it's back on take it off flight mode. This has solved random battery drains in the past for me (so it's not a structural solution for having longer battery life, just a tip if you're experiencing problems)

cybermoose89 says:

I do all this anyway XD

OldMillXxX says:

#16 - NOT seeing Store > Updates.  Specifically the Updates...

Lumia 928 GDR2/Amber

 

Nakazul says:

15. Buy your apps. There have been reports in the past of apps with commercial draining battery.

Tahiti Bob says:

On a side note, OEMs should put better batteries in our phones to start with.

scield says:

Anyone ever figure out that phantom Nokia 920 battery drain/overheating issue?  I've done everything I've found on forums and the internet to get rid of it to no avail.  Nokia pushed me to AT&T and they pushed me back to Nokia.  Useless.  Kinda sucks when I find my battery is hot enough to fry an egg on and the battery drained to almost empty in a matter of an hour or so.

danielgray says:

No, but to fix put in airplane mode and then turn airplane mode off

Sometimes only a restart helps. Same problem with the 820.

 

scield says:

Thanks for the replies, guys.  I know how to react to it, normally with a restart. I was just wondering if they ever fixed it or figured out what the issue was so we wouldn't have to deal with that. Thanks though.

peachy001 says:

Tip 18 - don't play solitaire

taymur says:

Yaaaaaa! It makes my device soooo hot, therefore the battery just clips its self off, and leaves the device and never comes back.

DVELOPinc says:

I guess I've been lucky. Pretty much everything has been the opposite of the tips except Glance, being I don't have it. I even keep Wifi Sharing on because I replaced my internet with an unlimited data plan. I can take phone off charger at 6:00AM and not put it back on the charger till around 10:00-11:00PM and haven't had a problem. Better add, yes, I play games such as Minion Rush, NFS... All day. Good tips though for those that do have issues.

RoboLoftie says:

So here's what I originally posted " Should have called it 15 tips and then had bonus tips for Lumia at the bottom imo."

 

Here's what was actually posted

"cant say that with my 920"

I dont even own a 920....

Double tap seriously drains battery. Turn it off, my 1320 still has more than 60% in a day, watch online video (wifi) for 3 hours, it's now down 34%

ayejay0601 says:

Thanks for the tips.  Even without all these tips though, I am getting amazing battery life on my new Lumia 1020.  I usually take it off the charger about 8am and usually dont need to recharge for over 32 hours!! (4pm the next day).  Its amazing.  With these tips, I bet I can go two days straight with no charge!

I am truly amazed at this!  My old Moto RAZR--I charged that thing like every 4 hrs.  It was awful.  I think it helps that there is no push gmail (which is a negative of course), but I have no complaints.  I also think switching from Verizon to AT&T helped me.  I feel like verizon is a bigger drain on battery--my old phone used to spend like 2 mins just finidng the network when I got off the subway (I think the fault is both Android and Verizon).

mpelti says:

Speaking of doubletap to wake, has anyone seen an issue on the 820 where the Touch menu in settings doesn't open?

My mom's car mount blocks her power button on her 820, but without that menu I can't get there.

Stop looking at your phone every second minute. I've seen lot of people do this. They will simply unlock the phone and then lock it again. Fiddling constantly with hardware buttons also wears them out

lukebrady81 says:

One tip you never mentioned is turning Facebook chat off. It saves tons of battery

So does anyone actually know why its 'not recommended' to leave Battery Saver on? =/ Because that seems like the most logical battery saving option.

920Walker says:

When battery saver is ON email doesn't automatically sync at the specified interval, it must be manually synced. Also, I don't believe programs selected to run in the background will run in the background.

Livetiles are not live any more. Basicly all data connections are closed. Using it at parties. No interruption and battery the whole night.

Pranay1995 says:

Some say switching to dark theme also helps saving battery as white one tends to be more bright. Is it true or just rumours? Anyone?

This is true for phones that use an AMOLED screen as it's the pixels themselves that are immiting light. As a result, a black pixel that isn't emmiting light isn't using any energy. So the more black pixels on your screen, the less battery power you're using up. White pixels on the otherhand use up the most energy. As such, a dark theme will conserve more power than the light theme.

This is not true for LCD screens as they use a backlight that is always on. The pixels themselves don't emit light but act as shutters that open and close, letting light through or blocking it. As such, a black pixel is simply a set of closed shutters that isn't allowing any light from the backlight to pass through the screen. But it is still consuming the same amount of energy as a white pixel with all it's shutters open.

Or you could read just the first sentences of the two paragraphs.

batkingnz says:

LOL!

Man WPCentral comments never fail to make me laugh :D

True though. Nice PSA.

JohnStrk says:

How about a dedicated WP task manager that lets us know exactly which apps are draining the battery and allows us properly end the task? Now wouldn't that be innovative?

tgr42 says:

Innovative, no.  Android has had this for ... how many years?  Windows has had this for ... how many decades?  Basic human decency though, yes.  So don't get your hopes up!  Haha.

taymur says:

Sarcasm, is a linguistic style of making fun of things, you should read about it.

leoniDAM says:

WP is innovative because you don't need to close the apps, but is the OS that provides to manage background process making the apps in a state called dormant so you don't need to worry about what apps is in the background!
But it seems that who has understood this are very few people...

jaywinjv says:

Dormant my a**. My phone heats up unless a background task is closed. 

JohnStrk says:

It's not all that innovative if I only open one app (like Facebook Beta or 6tag), use it for a few minutes, close it, and then for the next few hours watch the damn battery drain away like 10% an hour until I do a soft reset to stop it.  And I have followed just about every battery saving tip there is.  I only have a few apps allowed in background tasks like Amazing Weather, Insider, and WPCentral.  It's nice to at least have a few Live Tiles working through their background tasks.  

If I have to stop every single rogue battery draining app from running a background task, then what is the point of Live Tiles?  Not to mention that they still randomly stop working whenever they want to.  

WP really needs a dedicated task manager where the user can see which apps are still consuming battery and system resources, and allow the user to properly end this task.  Why is it so difficult?  In any version of Windows there is a task manager where I can see what program is running and what it’s doing.  WP 8.1 hopefully fixes these battery and background task issues!!

batkingnz says:

What does that app draining your battery have to do with whether it's innovative or not?

Darren Walsh says:

i find that when i have wifi to stay on i don't get all notifications from whatsapp, i have to go into it to see some new new messages ! does anyone else notice it ???

Pranay1995 says:

Your background task for WhatsApp must be blocked. Check on it..

Darren Walsh says:

it wasn't blocked it was the first thing i checked lol, it was a coupe of versions ago so i will try it again 

 

leoniDAM says:

Background task has nothing to do with push notification

AV2RY says:

I got this problem as well. BUT only when the chat is opened and my screen locks. After 40+ seconds you don't get notification (yeah I sat and checked it)) but when the charger is plugged in you always get notification between 1-5sec after it was sent no matter your chat is open (under lock screen) or your whatsapp is fully closed. AGAIN I have this problem ONLY when chat is open but screen is locked

nosyrbllewe says:

My phone died while I was reading this. LOL

Pranay1995 says:

Does dark theme play a role in battery saving? Anyone?

920Walker says:

I think only if you have a phone with AMOLED display. LCD uses the same energy regardless of color.

saBBfanBoy says:

Tried all of these tips weeks ago and my 920 still has the worst battery life ever!

exkerZ says:

I already do all of these things, but thanks anyways!

danielgray says:

Point 11, turn this off if there is no WiFi. I have no WiFi at work for 9 hours a day. If WiFi is always on then i am probably 20% less battery power at the end if the work day

donbreathe says:

I think Lumia 920 has serious battery problem, I have tried all these when advised by a Nokia Care Consultant but still experiencing fast battery drain. A few apps are also battery killers like Whatsapp, Weave, Waze and ProCamera just to mention a few. I love my Lumia 920 with features like glance and double tap so wouldn't want to turn off those cos I observed double tap really can take some juice but still not like chatting on whatsapp for 15mins or running Hipstamatic Oggl. I hope Windows Phone 8.1 will fix this and my next phone is certainly Lumia 1520 when it arrives Nigeria. I have seen that is the only phone of the Lumia brands that can withstand the bad mobile data services (HSPA+ at highest speed) available here.

AV2RY says:

Tip 11. Doesn't it waste more battery life if WiFi always ON?. I have it always on, if I'm not using my phone (L928) the battery stays for one full day at least..im sure it will waste less battery if WiFi turned Off (not ON when phone is in "sleep mode")

HoosierDaddy says:

What he seems to be implying is that the phone's data connection is drawing power when asleep and you can't turn it off except by having wi-fi turned on and that wi-fi uses less power asleep than the data.

But I also would like some confirmation on that. It does not seem logical to me and even if true, what happens when you aren't connected by wi-fi? Does just having wi-fi turned on stop data power usage even when not connected to wi-fi?

jayruguitar says:

Also, if you value having any sort of battery life; don't use Waze!

Lundon44 says:

It's odd but I never found the battery on my 1520 to be that impressive. I actually feel it's just slightly better than my 920. I still charge my phone every night. I use my phone often for browsing, streaming a dozen youtube videos a day, some instant messaging, a little periodic gaming and very little phone talking. Sometimes my battery seems to last longer than other days. I don't really know why. I've had days where I lost 4% battery an hour in airplane mode idle without use. Then I've seen days where I've seen it 4% over 9 hours in airplane mode idle. I don't know what causes that difference. I played almost 2 hours straight of Asphalt 8 last night (full brightness, audio on level 15) and lost just over 50% battery. I also typically see about 6% battery loss on 20 min of HD video streaming. I personally don't think I could go 2 full days without a charge. My battery read out is never accurate. No matter what it never shows more than 20ish hours remaining. Even on 100% battery. But what's odd is even in airplane mode when I was dropping 0.5% battery an hour it still showed approx. 21 hours remaining. Which is clearly incorrect. Personally I feel I'm more of a power user than most so if I get a days use out of it I'm content.

Bicpug says:

Sad when the only way to get the quoted battery life is to disable half the features.

pantsaregood says:

The point about changing automatic brightness is simply wrong. When automatic brightness is turned on, whatever is selected in the drop down menu is simply ignored. Automatic brightness (even when "high" is selected) will lower the display brightness far below that of "low" when in a dark area.

Disabling Bluetooth and NFC will increase battery life, but the improvement is fairly negligible.

Finally, everyone needs to understand that the Lumia 920 doesn't have "an overheating problem." The phone does get warm, but that does not imply that it is overheating. In fact, you'll notice that the phone gets warm towards the top - that's because the heatsink is working properly. If it wasn't, you wouldn't feel that heat.

Kram Sacul says:

I was about to say the same thing.  Automatic Brightness and the Brightness Level operate independently of eachother.

v0ha says:

Will try not to agree with point 3 - Set glance to peek (Lumia only)

 

If "peek" is used, I believe proximity sensor is additionally powered on if to compare with "interval" mode. So it should eat battery more. Correct me if I'm wrong.

wpguy says:

Tip 12.1 Uncheck Send information about Wi-Fi connections to help discover nearby Wi-Fi.

I know, the feature is supposed to provide crowd-sourced info to help everyone (including myself) locate nearby hotspots. There's enough people sending that data for me. Besides, if you don't have a usable mobile data connection, you can't use Data Sense's map nearby Wi-Fi feature and will have to find one the old-fashioned way: turn on Wi-Fi and watch the list populate as you walk to your venue of choice just down the street.

KeOnte Smith says:

DONT FORGET HIGH CONTRAST MODE, 0 ENERGY TO POWER BLACK PIXEL ON AMOLED SCREENS

Nice tips..but for what? I am very satisfied with the Lumia 920's battery.

batkingnz says:

Umm...

Most likely for people who aren't as satisfied as you?

leoniDAM says:

Please correct the tip 15 that is completly wrong and false.
And if you read the official documentation on dev.windowsphone.com ad if you konw how the RAM tipically works it is easy to understand.
So you have always proven reliable, please do not help to spread false myths!

elmacho says:

Yep..but Mark doesn`t seem to be around.Never participated anywhere in the discussion.

Closing apps does help. Not with basic apps of cause. But apps running in the background. A open camera app or a open gps related app can drain the battery in the background. Even if it might be a faulty background process... it stick to closing these apps. The rest i leave open of cause :)

leoniDAM says:

Again only (some of) the apps that use GPS can run in the background (for example apps like HERE Map, or Foursquare, can't but HERE Drive or GPX Viewer, or Hike and Bike can).
But you can block these apps in background task setting page, and you can close these apps using the back button.

pookyjoralyn says:

yesterday I was using my L920 when the battery reached like 48%, then I restarted it and it bumped up to 56%! :D

chmun77 says:

Simply put - make every setting to be off or to the lowest. Sometimes I wonder, why do we need smart phones nowadays? Gone were the days when the good old conventional Nokia phones lasted for days with just a single charged.  LOL!

Pacus1x says:

Another tip i would add is that if you are using some battery monitor app, the app will get running in the background and ironically draining more battery juice, so better to block those apps. For me, only creates more anxiety looking constantly how much battery remains in my Lumia 920... so i just uninstall that battery monitor app.

Mark Richey says:

While not directly related to the long-term battery life, I use wireless charging to keep me topped off almost all the time. Even with heavy use for music, video and internet use on the train during my commute. I get home and the battery has rarely moved much at all.

 

I have 2 chargers: 1 on my desk at work and 2 at home (only because I brought one of my cyan changers from work home after getting a charger that keeps my phone at an angle on my desk at work. The only time I have ever had issues was when I traveled and forgot the chanrger. But I remembered I had a USB cable from my car charger, brought that up to the hotel room, and plugged into my Surface RT. Life saver that! otherwise, I rarely connect to sync.

sdreamer says:

Most of these tips will barely get you any more battery life imo; maybe 20-30minutes more? That isn't much by my books. I can understand on Android to do these things to the dot, that OS seems to guzzle down battery. WP I haven't had that trouble. I leave everything on, and I still get great battery life (extremely rare do I get random drains though, happened twice in the last 6-7 months). I think smartphones need to be able to manage power themselves, and I think WP is pretty darn good at it. I never close apps, I like the OS decide how to handle that, BT and Wifi are always on, and Glance always on (though I did notice it uses the proximity sensor to know when it's in pocket so it shuts off when it knows its in your pocket).

The biggest factor from what I found is cellular data. Turn that off and you'll get multiple day battery life (ok maybe a bit over exaggerated, but I'm at 65%, off the plug for about 14 hours with moderate use). Or leave it on, and put a check mark on "Always restrict background data." You need GDR3 at least for this. This will prevent lives tiles from updating while on cellular data. Then I leave Wifi always on so things update as soon as I hit a wifi spot that I'm familiar with. Also allows me to download MMS without having to constantly go back and forth switching it on and off. Not to mention, those on low data plans (300 MB for me) this saves your data.

iTamma says:

Use black background-theme instead the white one, especially on AMOLED Displays.

batkingnz says:

Use black background-theme instead the white one, if you have an AMOLED Display.

 

Doesn't make an ounce of difference for the LCDs.

Mikez80 says:

Hello to all!
I have a doubt regarding this matter. The "Network Selection" option present in the "Mobile Network" options is better for the battery if it is chosen only the network you use, or is it better if you choose the automatic mode?
Thanks all for the future answers ;)

brod56 says:

I think that is equal, but I'm not sure :) Good question!

HoosierDaddy says:

Great article!

I did hit a snag though. I accidentally blocked the My Account app (T-Mobile) from running in the background. Apparently there is no way to manually unblock an app and I guess not all apps pay attention to the "unblock the next time the app is opened" check box because I've opened the app numerous times and turned the phone on and off and the app is still blocked.

jimski says:

Oh, and don't forget to get those plastic seat covers for your new Acura while your at it. Point is, while most of these are good tips, many take away from the overall experience, requiring you to take extra steps (like turning services on/off) all day long. Enjoy your phone and use it to its fullest. And rather than trying to get two days out of a charge, just charge your phone while your sleeping. A charger for for the office wouldn't hurt either. Finally, I challenge #11. While WiFi is more efficient than an LTE signal, WiFi only has only one power state, full on/off. While LTE has multiple states. So while your phone is sleeping, so is your wireless connection till it needs to wake up for a mail sync, etc. When it does wake, it only ramps up to the level required for the task, then back to sleep again. Meanwhile, WiFi is always on, maintaining that connection. I only recommend WiFi on while sleeping, if a wireless connection is not available.

Nice tips, I actually used some.

For email, you can setup gmail for push instead of pull.

nehmek says:

I've found that the Lumia 1020 has either great or terrible battery life. The first 1020 I had barely lasted 12 hours on standby in flight mode. I replaced it and now get 2 days with moderate to heavy use (all connections switched on, double tap and glance on, several apps with background tasks on). My brother bought a 1020 and it suffers the same problems as my first one. He is now looking to get it replaced as well.

There is definitely a battery problem with the 1020. I'm in Canada so I don't know whether international models face similar issues. These battery saver tips are great but they will not boost your battery life if the unit itself is defective.

I´d rather know how to clear my "other storage" 1,5 GB just tooooooo much.

wpguy says:

Is that 1.5 GB from Nokia's Storage Check or Phone Storage?

I just did a comparison on my phone between Nokia's Storage Check (other = 1.5 GB) vs. Phone Storage (other = 4.53 GB).

I noticed Nokia's Storage Check provides a much more granular report. Phone Storage's other value (4.53 GB) is approximately equal to the sum of Nokia's Storage Check values for application data (1.35 GB), maps (0.27 GB), temp (0.31 GB), what I presume to be resized temp photos for SkyDrive upload (0.93 GB), Office docs (0.02 GB), email (0.15 GB), ringtones (<0.00 GB), and other (1.5 GB).

batkingnz says:

I think WP8s storage check also takes in to account the APP DATA as well. For some Apps like Instagram and WeChat I have more app data than the size of the app.

AndrewL920 says:

I do not use mobile data connection because I am always at home and using WiFi. Is it okay to turn on WiFi even the phone is asleep? By default, WiFi turned off when asleep and reconnect when you wake up your phone. I think it is more battery saver if the WiFi is turned off when our phone is asleep. Any expert?

Sam Wong says:

11. Keep Wi-Fi on when screen switches off

Are you sure??

krotchitty says:

Lumia 925 T-Mobile; my longest time between charges (100% to 10%) so far is 3 days 7 hours;

I use 2G during the day and manually sync under LTE once an hour.

I turn OFF; Vibrate, location, WiFi, bluetooth, background tasks, internet sharing, tap&send, feedback, glance, double tap to wake, X box. Ring volume is set to 13, or 6 when calling. Screen brighness to low with auto adjust turned on, and I use the high contrast setting which makes most screens default to black, including the tiles. This and the vibrate made a significant difference, although I miss the colors.

Basically the majority of the time my phone is on standby 2G, sipping power. When I go to sleep, I turn on airplane mode. Takes 10 seconds to sync email once an hour, I get about 3 or 5 calls per day, take a few pics, 5 or so texts. Occassionally I will go the other direction and really use everything (without regard to battery life) and the phone still lasts a good 10 hours for me.

Other than not being able to sync my W8 phone with my W8.1 laptop, I like the phone.

 

Edit - almost forgot, I re-boot my phone once a day.

Help me!!! my Lumia 925 battery can't last more than 6 hours!!

karthikt94 says:

I keep my NFC feature turned on. But it doesn't take too much of the battery.

infestedd says:

helped me a lot, thanks

Until I looked at the check saying $7424, I accept that my neighbours mother was like they say actualy receiving money in there spare time from their laptop.. there uncles cousin started doing this less than 9 months and recently took care of the dept on their cottage and got a brand new BMW 5-series. read more at, w­w­w.w­o­r­k­s­7­7­.c­o­m

 

Thank you for the advice, but even with all these things done my Lumia 1520 keep draining battery fast ( 10% per hour ).

only 3 apps running in background ( Battery app, Facebook, Whatsapp ) all other apps are blocked.

is this normal or defect in my device.

Thanks.
